FIELD OF THE INVENTION

The present invention relates to a therapeutic agent capable ofintranasal administration comprising capsicum and/or capsaicinoids asthe therapeutic agent.

BACKGROUND OF THE INVENTION

Non-allergic rhinitis (“NAR”) affects millions of Americans, but themechanism(s) remains unknown. Transient receptor potential vanilloid-1(“TRPV1”) may be involved, as single dose studies of intranasalcapsaicin, a TRPV1 agonist, have demonstrated reduced nasal congestionin rhinitis subjects.

Chronic rhinitis is defined as persistent inflammation of the mucosalmembranes lining the nasal cavity, characterized by symptoms of nasalcongestion, rhinorrhea, sneezing and itching with or without post-nasaldrainage. (Settipane R A, Lieberman P. Update on nonallergic rhinitis.Ann Allergy Asthma Immunol 2001; 86:494-507; quiz-8. Wallace D V,Dykewicz M S, Bernstein D I, Blessing-Moore J, Cox L, Khan D A, et al.The diagnosis and management of rhinitis: an updated practice parameter.J Allergy Clin Immunol 2008; 122:S1-84.) A diagnosis requires theexclusion of structural abnormalities and underlying medical conditionsthat can manifest with rhinitis symptoms. (Settipane R A, Lieberman P.Update on nonallergic rhinitis. Ann Allergy Asthma Immunol 2001;86:494-507; quiz-8. Wallace D V, Dykewicz M S, Bernstein D I,Blessing-Moore J, Cox L, Khan D A, et al. The diagnosis and managementof rhinitis: an updated practice parameter. J Allergy Clin Immunol 2008;122:S1-84.) Broadly defined, rhinitis can be divided into inflammatoryand non-inflammatory rhinitis. (Wallace D V, Dykewicz M S, Bernstein DI, Blessing-Moore J, Cox L, Khan D A, et al. The diagnosis andmanagement of rhinitis: an updated practice parameter. J Allergy ClinImmunol 2008; 122:S1-84. Bernstein J A. Characteristics of Non-AllergicRhintiis. World Allergy Journal 2009; 2:102-5.)

Inflammatory rhinitis includes seasonal or perennial allergic rhinitis,entopic rhinitis and non-allergic rhinitis eosinophilic syndrome(“NARES”) whereas non-inflammatory rhinitis includes vasomotor rhinitis(“VMR”), commonly referred to as idiopathic rhinitis, and othernon-allergic rhinitis conditions such as rhinitis medicamentosa,gustatory rhinitis and hormonally-induced rhinitis. (Bernstein J A.Characteristics of Non-Allergic Rhintiis. World Allergy Journal 2009;2:102-5. Kaliner M. Classification of Nonallergic Rhinitis SyndromesWith a Focus on Vasomotor Rhinitis, Proposed to be known henceforth asNonallergic Rhinopathy. World Allergy Journal 2009; 2:98-101.) Sincepatients with allergic rhinitis often exhibit significant symptoms inresponse to irritant triggers, clinicians have postulated that allergicand non-allergic rhinitis components often co-exist and have thereforereferred to this condition as “mixed rhinitis” (“MR”). (Bernstein J A,Rezvani, M. Mixed Rhinitis: A New Subclass of Chronic Rhinitis. In:Kaliner M, ed. Current Review of Rhinitis, 2nd ed 2006; Philadelphia,Pa.:69-78.) Cross-sectional questionnaire survey studies have estimatedthat up to 75% of chronic rhinitis patients have either non-allergic ormixed rhinitis. (Settipane R A. Demographics and epidemiology ofallergic and nonallergic rhinitis. Allergy Asthma Proc 2001; 22:185-9.)

Currently non-allergic rhinitis (“NAR”) conditions are diagnoses byexclusion, as the mechanism(s) of this disorder is unknown andtherefore, there are no specific biomarkers or tests that establish adefinitive diagnosis. (Bernstein J A. Characteristics of Non-AllergicRhintiis. World Allergy Journal 2009; 2:102-5. Kaliner M. Classificationof Nonallergic Rhinitis Syndromes With a Focus on Vasomotor Rhinitis,Proposed to be known henceforth as Nonallergic Rhinopathy. World AllergyJournal 2009; 2:98-101.

Garay R.Mechanisms of vasomotor rhinitis. Allergy 2004; 59 Suppl 76:4-9;discussion-10.) The most popular mechanism postulated for non-allergicrhinitis has been an autonomic imbalance between the sympathetic andparasympathetic nervous system resulting in parasympathetichyperactivity leading to nasal congestion and drainage. (Baraniuk J N.Sensory, parasympathetic, and sympathetic neural influences in the nasalmucosa. J Allergy Clin Immunol 1992; 90:1045-50. Jones A S. Autonomicreflexes and non-allergic rhinitis. Allergy 1997; 52:14-9.) Recently,transient receptor protein (“TRP”) ion channel activation leading totrigeminal nerve depolarization has been postulated to play an importantrole in NAR, as these ubiquitous receptors can be activated by differenttemperatures, chemicals, osmolality and other physical stimuli that arewell recognized triggers of symptoms in NAR patients. (Bernstein J A.Characteristics of Non-Allergic Rhintiis. World Allergy Journal 2009;2:102-5. Brandt D, Bernstein J A.

Because mechanisms of NAR are poorly elucidated, there are still only afew medications approved for the treatment of this condition. Althoughclinical studies have found that the intranasal antihistamines,azelastine and olopatidine, intranasal ipratropium bromide andintranasal corticosteroids are relatively effective in relievingsymptoms related to NAR, it is unclear how they are mechanisticallyexerting their effect.

Capsaicin is a pungent substance found in capsicum spp. (red pepper)that is known to ablate sensory nerve fibers in NAR patients leadinginvestigators to postulate a role for afferent C-fibers in NAR. (Blom HM, Van Rijswijk J B, Garrelds I M, Mulder P G, Timmermans T, Gerth vanWijk R. Intranasal capsaicin is efficacious in non-allergic,non-infectious perennial rhinitis. A placebo-controlled study. Clin ExpAllergy 1997; 27:796-801.) This observation was supported by earlyplacebo controlled studies that treated NAR patients with topicalcapsaicin and found significant improvement in symptom scores comparedto placebo without changes in levels of mast cell mediators (i.e.,leukotrienes, prostaglandin (PGD2) or tryptase) indicating that theeffect of this medication was not due to reduction in mast-cell mediatedinflammation. (Blom H M, Van Rijswijk J B, Garrelds I M, Mulder P G,Timmermans T, Gerth van Wijk R. Intranasal capsaicin is efficacious innon-allergic, non-infectious perennial rhinitis. A placebo-controlledstudy.

Clin Exp Allergy1998; 28:1351-8.)

Subsequently, it was discovered that capsaicin exerted its activitythrough activation of the TRP vanilloid-1 (“TRPV1”) ion channel whichleads to desensitization of nasal sensory neural fibers and reduction innasal hyperresponsiveness. (Seki N, Shirasaki H, Kikuchi M, Sakamoto T,Watanabe N, Himi T. Expression and localization of TRPV1 in human nasalmucosa. Rhinology 2006; 44:128-34.) Single intermittent short termdosing studies with intranasal capsaicin in AR and NAR have confirmedthat intranasal capsaicin is effective at reducing nasal congestion anddischarge. (Blom H M, Van Rijswijk J B, Garrelds I M, Mulder P G,Timmermans T, Gerth van Wijk R. Intranasal capsaicin is efficacious innon-allergic, non-infectious perennial rhinitis. A placebo-controlledstudy.

However, the concentration of capsaicin used and found effective inthese studies, ranging from 30 ppm to 300 ppm, was very irritating andrequired a physician to co-administer a local anesthetic making itimpractical and intolerable for patients to self-administer thecomposition or use this treatment long term. (Blom H M, Van Rijswijk JB, Garrelds I M, Mulder P G, Timmermans T, Gerth van Wijk R. Intranasalcapsaicin is efficacious in non-allergic, non-infectious perennialrhinitis. A placebo-controlled study.

Applicant is notaware of any prior studies disclosing, teaching or suggesting acomposition comprising capsicum/capsaicin present in an effectiveconcentration, that may be self-administered as a mono-therapy by theuser. Furthermore, Applicant is not aware of any studies demonstratingclinical efficacy of capsicum/capsaicin at concentrations 10% or less ofthe dosages used in previous rhinitis clinical trials. What is needed inthe industry is a composition comprising capsicum/capsaicin that may beadministered intranasally in an effective concentration, allowing theuser to self-administer the composition without the need for the user tovisit a physician's office for each treatment.

According to an embodiment of the present invention, it has beenunexpectedly discovered that certain concentrations of capsicumcomprising capsaicinoids, including capsaicin, may be self-administeredby the user and provide relief from symptoms. Previously it has not beenpossible to deliver an effective concentration of capsicum intranasallywithout causing such discomfort to the user requiring the use of anadjunct to desensitize the nasal membranes in order to administer thecapsicum. What is needed in the industry is a composition comprisingcapsicum/capsaicin that is effective in relieving symptoms, but can beused without causing discomfort to the user or requiring adjunct agents.

Applicant is not aware of any prior studies investigating the immediateor short-term relief of symptoms provided by the intranasaladministration of capsicum as disclosed in the present application. Inaddition, Applicant is not aware of any prior studies disclosing that alow homeopathic dilution of capsicum is clinically effective for thetreatment of rhinitis.

What is needed in the industry is a nasally administered compositionthat provides a rapid onset of relief for rhinitis subjects. What isneeded in the industry is an intranasally administered compositionhaving a rapid onset of action and significant reduction of symptoms,that is an attractive mono-therapy or adjunctive therapy for themanagement of rhinitis symptoms, including, but not limited to, chronicrhinitis symptoms. What is needed in the industry is an intranasallyadministered composition having a quick onset of action with an averagetime to first relief in less than thirty minutes, less than fiveminutes, and even less than one minute.

Currently available over the counter (“OTC”) medicated nasal sprays forthe relief of rhinitis symptoms necessarily contain labels with awarning indicating that the product should not be used for more thanthree days. Extended use of these known products leads to the occurrenceof rebound congestion and the potential for addiction. These known OTCproducts are not suitable for use by those with symptoms that lastlonger than three days, including those suffering chronic conditions,and those suffering from chronic rhinitis symptoms.

What is needed in the industry is an intranasally administeredcomposition that is well-tolerated with prolonged treatment results andwith substantially no alteration or impairment in olfaction. What isneeded in the industry is an intranasal composition wherein usersexperience little to no rebound congestion. What is needed in theindustry is an intranasal composition wherein use of the compositionresults in an improvement in olfaction versus placebo after continueduse.

What is needed in the industry is an intranasally administeredcomposition wherein during a treatment period is significantly effectiveat improving nasal congestion, sinus pressure, sinus pain and headachecompared to placebo. What is needed in the industry is a nasallyadministered composition that provides safe, sustained relief over thecourse of a treatment period. What is needed in the industry is anasally administered composition that works fast and is safe.

What is needed in the industry is an intranasally administeredcomposition that provides relief from at least one of nasal congestion,sinus pressure and sinus pain with an improved therapeutic response thatcontinues over time with nasal congestion, sinus pressure, sinus painand headache significantly improved at about 5, 10, 15 and 30 minutesand persists for nasal congestion and sinus pain through the longesttime point measured.

DETAILED DESCRIPTION OF THE INVENTION

Capsicum is derived from several Capsicum pepper varieties. The Capsicumvariety utilized in embodiments of the present invention is derived fromcayenne pepper plants, which may comprise at least one of Capsicumbaccatum, Capsicum annum, and Capsicum frutescens, or a combinationthereof. The capsicum comprises capsaicin, dihydrocapsaicin, andnordihydrocapsaicin and possibly other capsaicinoids as activeingredients. The capsicum utilized in an embodiment of the presentinvention may comprise an all natural, water soluble and/or solubleliquid suspension material. The aqueous solution of capsicum maycomprise a homeopathic dilution of capsicum. The aqueous solution ofcapsicum may comprise a homeopathic dilution of Capsicum annum. The useof capsicum comprising capsaicin, dihydrocapsaicin, nordihydrocapsaicin,and possibly other capsaicinoids as opposed to synthetic capsaicin mayallow for repeated use and effective delivery without causing anuncomfortable and/or intolerable burning sensation in the nasal mucosaof the user.

An embodiment of the invention relates to a method of treating a humanin need thereof, by delivering the composition described herein andwherein capsicum including, but not limited to, capsaicin,dihydrocapsaicin, and nordihydrocapsaicin is the effective agent. Themethod comprises the intranasal administration of capsicum comprising,but not limited to, capsaicin, dihydrocapsaicin, and nordihydrocapsaicineffecting the relief of at least one rhinitis symptom. It will beapparent to one skilled in the art that the following are examples offormulations and many more formulations are possible and fall withinembodiments of the present invention as disclosed and claimed herein.

Example 1

It is hypothesized that capsicum, comprising capsaicinoids, includingcapsaicin, and possibly other ingredients in Applicant's composition,used for relief of rhinitis and allergic symptoms act via activation ofTRP-family receptors. Applicant has developed an in vitro fluorometricassay to measure receptor activity in the presence of variousconcentrations of capsaicin/capsaicinoids. The activation of thereceptors in the in vitro assay correlates with Applicant's demonstratedsymptom relief as evidenced in the examples below. Specifically, thegoal of the in vitro assay is to quantitatively measure TRPV activationto determine the dose response of airway component cells to Applicant'scompositions comprising capsaicin/capsaicinoids. To this end, Applicantdeveloped a new assay for transient receptor protein vanilloid (“TRPV”)activation in cells. The assay is fluorometric in nature, relying upon acalcium-binding fluor, Fura-4. (available from Invitrogen Life Sciencesand other vendors). Fura-4 fluoresces at a specific wavelength when itbinds to calcium. Cells are loaded with Fura-4, and under digitalconfocal observation exposed to capsaicin/capsaicinoid containingcompositions. The signal intensity over single cells is captured for0.5-5 minutes and the result expressed as normalized (to baseline)signal intensity over time.

As shown in FIG. 1, the activation of a calcium channel by thecomposition will result in an increase in fluorescence. In the case ofTRPV channels, since the channels are activated transiently (hence thename, Transient Receptor Potential V channels, TRPV,) the signalsrapidly diminish in 1-2 minutes. The effects of thecapsaicin/capsaicinoid-containing compositions to TRPV1 knockout cells(gene targeted ablation of the TRPV1, capsaicin receptor) is shown.Applicant performed the assay using compositions comprising varyinglevels of capsaicin/capsaicinoids, shown in FIG. 1, and achieved adose-response, demonstrating that the in vitro assay distinguishesresponses of about 1 ppm (n=14), 0.5 ppm (n=12), 0.25 ppm (n=8) and 0.10ppm (n=4) concentration of total capsaicinoids, including capsaicin. Theconcentration at 1 ppm is about 0.0064% w/w capsicum, 0.5 ppmconcentration is about 0.0032% w/w capsicum, 0.25 ppm concentration isabout 0.0016% w/w capsicum, and the 0.10 ppm concentration is about0.0008% capsicum. Responses are statistically different at the peak ofactivation (P<0.05). Mean (curves) and standard deviation (verticallines) of fluorescent intensities of cells treated with the indicatedcompositions are shown. Formulations were perfused at time=0, andintensity plotted vs. time (seconds). Each signal was normalized to thebaseline reading of that cell or part of a cell before infusion (toaccount for differential loading of Fura-4 and baseline differences inintracellular calcium levels). Applicant is not aware of any known invitro studies that show the receptor response resulting from theadministration of homeopathic doses of capsicum/capsaicinoid containingcompositions.

In addition to the dose-response, the assay demonstrates that there isno calcium uptake in the blank sample (no aromatics, no capsaicinoids,n=1, Preliminary Data). Cells with gene targeted ablation of the TRPV1channel (“TRPV1 KO”) also show no increase in signal (n=1, PreliminaryData), supporting that the signal activated by thecapsaicin/capsaicinoid containing formulations is indeedTRPV1-dependent. Applicant concludes from the data that the capsaicinresponse is primarily due to TRPV1, but expects that other TRPs willrespond to the aromatics and the affect may be different in differentcell types.

The results of this study indicate that a range of capsaicinoids fromabout 0.1 ppm to about 1 ppm total capsaicinoids significantly activatesthe TRPV channels over the controls. Applicant may easily extrapolatethis data to reasonably infer and support a concentration range ofcapsaicin/capsaicinoids that will be effective at relieving rhinitissymptoms in humans in need thereof. Various formulations andconcentrations of capsaicin/capsaicinoids have been used by Applicant tosuccessfully treat these symptoms as shown in Examples 2-5 below. Thefollowing examples of formulations of compositions wherein the totalcapsaicinoids provide quick, effective relief from symptoms.

Example 2

A clinical study was performed to assess the efficacy and safety of anewly formulated intranasally administered capsicum composition (“ICX”)used continuously over a two week treatment period in chronic rhinitissubjects who have a significant component of NAR. The ICX formulationcomprises from about 0.00060% to about 0.010% w/w, or comprising about0.1 to about 2.0 ppm total capsaicinoids, about 0.0020% to about 0.0080%w/w, resulting in about 0.3 to about 1.5 ppm total capsaicinoids, orpreferably about 0.0030% to about 0.0080% w/w, resulting in about 0.5 toabout 1.5 ppm total capsaicinoids. The ICX formulation further comprisesrosemary extract at a concentration of about 0.02% to about 0.25% w/w,eucalyptol at a concentration of about 0.07 to about 0.15%, vegetableglycerin at a concentration of about 3.5% to about 5.0% w/w, ascorbicacid at a concentration of about 0.10% to about 0.90% w/w and sea saltat a concentration of about 0.40% to about 1.2% w/w. One embodiment mayalso comprise potassium sorbate at a concentration of about 0.05% toabout 0.30%. One embodiment of the ICX formulation comprises about0.0064% w/w capsicum, about 0.11% w/w eucalyptol, about 0.067% w/wrosemary extract, about 0.4 to about 0.7% w/w each ascorbic acid and seasalt, about 4.4% w/w vegetable glycerin, in purified water.

Forty-two informed, consented patients with a significant component ofNAR were randomized to receive either ICX (n=20) or a filtered watercontrol (n=22) administered 1-2 puffs in each nostril twice daily over 2weeks. The primary endpoint was change in total nasal symptom scores(“TNSS”) from baseline to end of study. Secondary endpoints includedchanges in individual symptom scores (nasal congestion, sinus pain,sinus pressure, headache, sneezing, rhinorrhea, and post-nasal drainage)over two weeks and average time to first relief. Mean TNSS andindividual symptom scores were also recorded after single dosing withICX vs. placebo at 5, 10, 15, 30 and 60 minute intervals. Rhinitisquality-of-life domains at end of study, and use of rescue medicationand safety endpoints were also analyzed. All data was analyzed by theStatistical Analysis System (“SAS”).

Statistically significant differences in changes from baseline to end ofstudy between the ICX and placebo groups were observed for TNSS and eachindividual symptom (p<0.01). The average time to first relief for ICXsubjects was 52.6 seconds which was significantly less than placebo(p<0.01). For ICX subjects, nasal congestion, sinus pain, sinus pressureand headache were significantly improved at 5, 10, 15, 30, whichpersisted up until 60 minutes for nasal congestion and sinus pain(p<0.05). No significant difference between groups in adverse events orrescue medication was observed. ICX subjects experienced no reboundcongestion and demonstrated an improvement in olfaction versus placeboat the end of study visit.

This is the first controlled clinical trial to demonstrate that the ICXcomposition comprising capsicum provides a rapid onset of relief forrhinitis subjects, while also providing safe, sustained relief over thecourse of the two week treatment period.

This was a randomized, placebo controlled, double-blind parallel studyincluding patients previously diagnosed with non-allergic rhinitis(“NAR”) or “mixed rhinitis” defined as allergic rhinitis (“AR”) withsignificant NAR triggers. (Bernstein J A. Characteristics ofNon-Allergic Rhintiis. World Allergy Journal 2009; 2:102-5. Bernstein JA, Rezvani, M. Mixed Rhinitis: A New Subclass of Chronic Rhinitis. In:Kaliner M, ed. Current Review of Rhinitis, 2nd ed 2006; Philadelphia,Pa.:69-78

Forty-two patients between the ages of 18-60 were enrolled in thisstudy. All subjects signed an informed consent approved by a central IRBprior to enrollment. Subjects were required to have a diagnosis of NARwith or without an allergic component (i.e. mixed rhinitis) for at leastsix months prior to enrollment. Mixed rhinitis was defined as being skinprick test positive, defined as a wheal 3 mm in diameter than salinecontrol with surrounding erythema, to one or more aeroallergens inaddition to having significant symptoms induced by chemical irritants,strong odors, weather or temperature changes. (Bernstein J A, Rezvani,M. Mixed Rhinitis: A New Subclass of Chronic Rhinitis. In: Kaliner M,ed. Current Review of Rhinitis, 2nd ed 2006; Philadelphia, Pa.:69-78.)The magnitude of each subject's non-allergic rhinitis component wasconfirmed using a gender specific irritant index score previouslydemonstrated to correlate with a diagnosis of NAR or MR. (Bernstein J A.Characteristics of Non-Allergic Rhintiis. World Allergy Journal 2009;2:102-5.) Twenty subjects received ICX and 22 received placebo control(filtered water). Thirty-three of the 42 participants had a diagnosis ofMR, and 9 had an NAR diagnosis. These diagnoses were evenly distributedbetween the ICX and placebo groups. All subjects enrolled into thisstudy and randomized to ICX or placebo control and who received at leastone dose of study drug were included in this intent-to-treat analysis.

All subjects were required to have previously experienced symptomaticrelief while using their currently prescribed rhinitis medications andwere required to exhibit moderate to severe rhinitis symptoms while offthese medications at the time of randomization. Symptom severity wasdefined as a morning or evening nasal congestion and/or post nasaldrainage score of at least 5 out of 10 on three separate symptomassessments during the 7 day pre-randomization medication wash-outperiod. This included being symptomatic at least 24 hours prior to andincluding the day of randomization. Subjects were required to complywith all study related visits and procedures and had to be in generallygood health without any uncontrolled chronic health problems.

Subjects were excluded if they had an acute sinus infection in the past30 days, had a history of nasal polyps or other nasal structuralproblems, were treated with oral corticosteroids in the past 7 days,were active smokers or had passive smoke exposure at least six monthsprior to enrollment. Finally, pregnant women were not permitted toparticipate and women of child bearing age were required to useacceptable birth control throughout the study.

There were a total of three study visits and one interim phone call, asshown in FIG. 2.

During visit one, subjects who signed an informed consent and met allinclusion/exclusion criteria (except for symptom scores), were removedfrom all rhinitis medications for 7 days to determine if they wouldfulfill the symptom entry criteria. They were permitted to usediphenhydramine 25 mg up to 200 mg/day as rescue medication throughoutthe study. During visit two, subjects who fulfilled allinclusion/exclusion criteria including the symptom score criteria, wererandomized to receive either ICX or filtered water placebo, 1-2 puffseach nostril, twice daily. During visit 2, subjects were given theirfirst dose of study drug or placebo in the office. Using the stopwatchmethod, subjects clicked the stopwatch when they felt the first onset ofsymptom relief. (Black P, Max M B, Desjardins P, Norwood T, Ardia A,Pallotta T. A randomized, double-blind, placebo-controlled comparison ofthe analgesic efficacy, onset of action, and tolerability of ibuprofenarginate and ibuprofen in postoperative dental pain. Clin Ther 2002;24:1072-89.) They were then immediately instructed to complete a symptomscore card. Subjects also completed symptom score cards at 5, 10, 15, 30and 60 minute intervals during this visit.

An interim phone call to the subject's home was made 7 days later toconfirm compliance with completing home symptom diaries and to assessfor adverse events and rescue medication requirements. The study endedat visit three, two weeks after randomization (visit 2).

During each visit, all subjects had a directed medical history, nasalexamination, and a review of concomitant and/or rescue medications.During visits 1 and 3, all subjects underwent acoustic rhinometry andautomated olfactometry to assess nasal congestion and smell,respectively. (Bernstein J A, Bernstein I L. A novel case ofmealworm-induced occupational rhinitis in a school teacher. AllergyAsthma Proc 2002; 23:41-4. Rezvani M, Brandt D, Bernstein J A, HastingsL, Willwerth J. Investigation of olfactory threshold responses inchronic rhinitis subtypes. Ann Allergy Asthma Immunol 2007; 99:571-2.)Pregnancy tests were performed on all women of child bearing age atvisits 1 (screening) and 2 (randomization). Rescue medication andadverse events were assessed at visit 2, during the interim phone call,and at visit 3.

Symptom scores and rescue medication requirements, consisting ofdiphenhydramine 25-50 mg up to four times a day (maximum dose 200mg/day), were recorded on subject's home diaries over the three weekstudy period.

The primary endpoint was the change in the 12 hour reflective total TNSSrecorded by the patient each evening in a daily diary, from baseline tothe end of the study (2 weeks). TNSS was a composite score that includednasal congestion, post-nasal drainage, sneezing, rhinorrhea, sinus pain,sinus pressure and headache. These symptoms were chosen based on the“Allergies in America survey” which cited these as the worst symptomsand/or co-morbid conditions experienced by chronic rhinitis patients.(Blaiss M S, Meltzer E O, Derebery M J, Boyle J M. Patient andhealthcare-provider perspectives on the burden of allergic rhinitis.Allergy Asthma Proc 2007; 28 Suppl 1:S4-10.) Each symptom was rated on a10 point Likert scale and therefore, the highest possible TNSS was 70,where a higher score reflects more intense symptoms.

Secondary endpoints included changes in 12 hour reflective symptomscores of nasal congestion, post-nasal drainage, sneezing, rhinorrhea,sinus pain, sinus pressure and headache recorded at home daily bypatients on diary cards over a 2-week period and the time to firstrelief of symptoms recorded in the physician office at visit 2, aftersingle dosing with ICX or placebo.

Other endpoints included changes in symptom scores (TNSS, nasalcongestion, post-nasal drainage, sneezing, rhinorrhea, sinus pain, sinuspressure and headache) at the time to first relief and assessment ofrescue medication requirements during the entire 2 week study period.

Adverse events, olfaction as measured using an automated olfactometer(Osmic Enterprises, LLC) (Rezvani M, Brandt D, Bernstein J A, HastingsL, Willwerth J. Investigation of olfactory threshold responses inchronic rhinitis subtypes. Ann Allergy Asthma Immunol 2007; 99:571-2),and nasal congestion using an acoustic rhinometer (Ecco Vision, HoodInstruments, Pembroke, Mass.) to assess for increased nasal resistance(i.e., a rebound effect) (Bernstein J A, Bernstein I L. A novel case ofmealworm-induced occupational rhinitis in a school teacher. AllergyAsthma Proc 2002; 23:41-4) were recorded and assessed prior torandomization while off all rhinitis medications and at the end ofstudy.

The sample sizes for the ICX drug and placebo control groups were chosenbased on feasibility and other intranasal capsaicin studies thatreported clinically meaningful results. (Blom H M, Van Rijswijk J B,Garrelds I M, Mulder P G, Timmermans T, Gerth van Wijk R. Intranasalcapsaicin is efficacious in non-allergic, non-infectious perennialrhinitis. A placebo-controlled study. Clin Exp Allergy 1997;27:796-801.) For sample sizes of 20 per group, the power was 80% todetect a difference of 2 units in TNSS mean scores from baseline to 14days between the drug and placebo groups assuming a 2-tailed alpha=0.05.The effect size (ratio of mean difference to TNSS standard deviation)was equal to 0.8.

For all analyses a p-value<0.05 was used to judge statisticalsignificance unless stated otherwise. The analyses were performed usingSAS for Windows, version 9.2, SAS Institute, Cary N.C.

Subject demographics: The demographic characteristics of the subjectpopulation are summarized in Table 1.

Percentrelative change of each symptom was larger for ICX72, compared withplacebo, except rhinorrhea. Mean changes from baseline to end of studywere significantly different between ICX72 and placebo for TNSS, nasalcongestion, sinus pressure, sinus pain and headache (p < 0.006 for eachvariable determined by Bonferroni adjustment, overall p-value = 0.05).

The mean differences between the ICX and placebo groups with respect tochanges in TNSS, nasal congestion, sinus pressure, sinus pain andheadache from baseline to end of study were statistically greater forICX compared to placebo (p<0.01). FIG. 3 illustrates the magnitude ofthis effect for TNSS and the individual symptoms that significantlyimproved. No significant differences between groups in changes frombaseline to end of study were observed for sneezing, post-nasal drip andrhinorrhea (p>0.05).

Times to first relief: The average time to first relief for ICX wasequal to 52.6 seconds (0.8 min), which was significantly lower than theaverage time of first relief for placebo subjects (p<0.01). Eightypercent of subjects receiving ICX experienced first relief in less thanone minute compared to 45% of subjects receiving placebo (p<0.05).Symptoms that significantly improved at time to first relief were nasalcongestion, sinus pressure and headache (p<0.05) as shown in Table 3.

Four patients had missing data atfirst relief for each symptom. When a symptom at first relief wasmissing, less relief was assumed than was determined from all reportedsymptom changes at first relief, after adjusting for baseline. Theminimum values at first relief of missing data were symptom-specific.Mean symptom changes in the placebo group were obtained from Tobitanalysis, which accounts for the upward bias of changes calculated fromobserved data only. The probability of unreported symptoms reflectingless relief than the minimum relief of all other patients was combinedwith the probabilities of the observed symptom values at first relief,to estimate mean changes at first relief of each symptom for the placebogroup. Note: For each variable, baseline differences between groups werenot statistically different (p > 0.05). Mean changes from baseline tofirst relief were significantly different between ICX72 and placebo forsinus pressure and headache only (p < 0.006 for each variable determinedby Bonferroni adjustment, overall p-value = 0.05).

Improvement in TNSS and Symptoms Scores for Intranasal CapsaicinCompared to Placebo At Fixed Time Periods: This analysis requiredsubjects to complete symptom score questionnaires at fixed time periodsbeginning at 5 minutes up to 60 minutes after the first dose.Differences were statistically significant for nasal congestion, sinuspressure, sinus pain and headache at 5, 10, 15 and 30 minutes whichpersisted for nasal congestion, sinus pressure and sinus pain up to 60minutes (p<0.05).

Rescue medications: Fewer subjects in the ICX group (n=6; 30% ofsubjects) compared to the placebo group (n=10; 45% of subjects),reported rescue medication usage during the first week afterrandomization.

Similarly, fewer subjects in the ICX group (n=4; 20% of subjects) versusthe placebo group (n=10; 45%) reported use of rescue medications duringthe second week after randomization.

Safety Analyses:

Olfactometry: The olfactory threshold means of ICX and placebo subjectsat baseline and end of study are summarized in Table 4.

TABLE 4 Mean Change from Baseline to End of Study (Standard Error) ofOlfactory Thresholds for ICX72 and Placebo Groups. ICX72 (N = 14)Placebo (N = 17) Change: Baseline- Change: Baseline- Baseline EndBaseline End Olfactory 6.7 −1.0 6.1 +0.1 Threshold (0.4) (0.6) (0.6)(0.5) N = number of patients A negative change (higher value at end ofstudy) indicates improved olfaction. Baseline (defined as data collectedduring visit 2 pre-drug) differences between groups were notsignificantly different (p > .05). Mean changes from baseline to end ofstudy were not significantly different between ICX72 and placebo groups(p > .05). End of study means were significantly different between ICX72(7.7) and placebo (6.0) (p < .05).There were no significant differences between baseline or the changefrom baseline to end of study olfactory threshold means for ICX andplacebo subjects (p>0.05). However, ICX subjects, had significantlyhigher olfactory threshold means compared to placebo at visit 3 (p<0.05)indicating that their sense of smell was actually improved during theend of study visit compared to placebo.

Acoustic Rhinometry: There was no significant difference in nasal meancross sectional areas or volumes at baseline (when subjects were removedfrom rhinitis medications) compared to end of study between ICX andplacebo subjects (data not shown). This indicates that increased nasalresistance, which is what would be seen with rebound nasal congestion,was not a side effect when ICX was used continuously over 2 weeks.

Adverse Events: There was no significant difference between ICX andplacebo in reported adverse events. Reported adverse events includedincreased nasal congestion, headaches, post-nasal drainage, rhinorrhea,transient stinging/burning, blood tinged mucus and fatigue. Ten percentof subjects on ICX and 27% on placebo, respectively (p=0.24) reportedadverse events during the first week after randomization whereas, 45% ofsubjects on ICX and 32% on placebo (p=0.53) reported adverse eventsduring the second week after randomization.

The results of this study clearly demonstrate that continuous treatmentwith ICX over a two week period was significantly effective at improvingTNSS, nasal congestion, sinus pressure, sinus pain and headache comparedto placebo. Furthermore, ICX has a quick onset of action as the averagetime to first relief was less than one minute (52.6 seconds). This rapidimprovement was most pronounced for nasal congestion, sinus pressure andsinus pain.

Interestingly, this improved therapeutic response continued over time asnasal congestion, sinus pressure, sinus pain and headache weresignificantly improved for ICX versus placebo at 5, 10, 15 and 30minutes and persisted for nasal congestion and sinus pain up until 60minutes. Thus, the rapid onset of action resulting in significantreduction of symptoms makes ICX an attractive mono-therapy or adjunctivetherapy for the management of chronic rhinitis symptoms.

Prolonged treatment with ICX resulted in no alteration in olfaction andin fact appeared to improve olfaction in patients receiving ICX versusplacebo at end of study. Furthermore, subjects receiving ICXcontinuously over two weeks showed no rebound congestion as reflected byimproved symptom scores and no change in nasal cross sectional areameasured by acoustic rhinometry. Other than a transient stingingsensation, ICX was well tolerated.

Several important points regarding this study should be emphasized.First, this is the first study to demonstrate that continuous dailytreatment with a composition comprising a lower concentration ofintranasal capsicum (ICX) over a two week period is safe and effectiveat improving chronic rhinitis symptoms. Second, in that all subjects inthis trial were required to have a significant component of NAR as partof their enrollment criteria, the beneficial effect of ICX supports animportant mechanistic role for TRP ion channels, specifically TRPV1 inNAR.

The robust effect of ICX on improving rhinitis symptoms and headachessuggest overlapping neurogenic mechanistic pathways for MR, NAR andheadaches, perhaps in part involving TRP ion channels, that requirefurther investigation. (Rapoport A M, Bigal M E, Tepper S J, Sheftell FD. Intranasal medications for the treatment of migraine and clusterheadache. CNS Drugs 2004; 18:671-85.)

There are several potential limitations of this study that warrantdiscussion. First, similar to what has been encountered for otherintranasal medications (Banov C H, Lieberman P. Efficacy of azelastinenasal spray in the treatment of vasomotor (perennial nonallergic)rhinitis. Ann Allergy Asthma Immunol 2001; 86:28-35.), it was notpossible to formulate a placebo that caused mild transient stingingsimilar to the ICX formulation used in this trial. However, in order toensure that the study remained blinded to the subject, both the clinicalresearch coordinator and investigator used common written instructionsto direct the patient through different procedures thereby limiting anyunnecessary conversations during the study visits that could bias thesubject or coordinator. Second, it is worth noting that subjectsreceiving placebo in some instances experienced modest improvement inTNSS and specific symptom scores compared to baseline. The therapeuticeffect of placebo in clinical trials has been well established. (SpectorS L. The placebo effect is nothing to sneeze at. J Allergy Clin Immunol1992; 90:1042-3.) However, the finding that ICX had a faster onset ofaction and greater overall improvement in nasal congestion and TNSScompared to a placebo control at various time points throughout thestudy is a testimonial to its robust therapeutic benefits.

In summary, this is the first controlled clinical trial to demonstratethat ICX provides a rapid onset of relief for rhinitis subjects with anon-allergic component, while also providing safe, sustained relief overthe course of the two week treatment period.
